People usually think about it like this. If a battery is rated for 1,000 cycles, and one full charge lets you drive 500 km, then the battery should last about 500,000 km. But there is one important thing missing from this calculation: regenerative braking. In an electric vehicle, when you slow down or brake, energy flows back into the battery and is then used again for driving. This process still counts as battery usage. For example, if during a drive the energy reused throug
